Vedanta Aluminium, the country’s largest aluminium producer, has successfully increased the capacity of its Lanjigarh Refinery to 5 million tonnes per annum (MTPA), marking a major milestone in India’s aluminium value chain and reinforcing the nation’s push toward self-reliance in critical metals. With the expanded capacity, the Lanjigarh facility has become the largest alumina refinery in India and now ranks as the second-largest alumina refinery globally outside China.
The expansion raises India’s overall alumina refining capacity to nearly 13 MTPA, positioning the country as the world’s third-largest alumina producer. The Lanjigarh refinery alone accounts for approximately 38 percent of India’s total alumina production, making it the single largest contributor at one location.
The scale-up comes at a time of accelerating domestic demand for aluminium across sectors such as infrastructure development, automotive and electric vehicles, renewable energy, construction, railways, and aerospace. Vedanta Aluminium said the milestone reflects its long-term strategy to build a globally competitive aluminium ecosystem that supports India’s industrial growth.
Alongside the capacity expansion, the refinery recorded its highest-ever monthly alumina output in November, producing 254 kilo tonnes. This represented an 8 percent increase over the previous month and a 68 percent rise compared to the same period last year. The record performance was supported by operational improvements, including the handling of more than 700 rail rakes in a single month, the lowest specific power consumption achieved in the past 20 months, and conversion costs reduced to an 18-month low through process optimisation and improved resource efficiency.
Rajiv Kumar, Chief Executive Officer of Vedanta Aluminium, said aluminium is a strategically important metal for India’s industrial development and the vision of Aatmanirbhar Bharat. He noted that scaling Lanjigarh to 5 MTPA is both a capacity achievement and a step toward creating a resilient, world-class aluminium value chain for the country.
Pranab Kumar Bhattacharyya, Chief Executive Officer of Vedanta’s Alumina Business, said the expansion reflects the engineering strength and dedication of the teams involved. He added that from concept to commissioning, the project has been driven by precision, agility, and collaboration, with continued focus on efficiency, safety, and reliable large-scale performance.
Originally commissioned as a 2 MTPA greenfield refinery, Lanjigarh began its expansion journey in 2020. Beyond production growth, Vedanta Aluminium continues to invest in community development initiatives around education, healthcare, sports, and skill development, aligning industrial progress with social advancement.
Vedanta Aluminium, a business of Vedanta Limited, produced 2.42 million tonnes of aluminium in FY25, accounting for more than half of India’s output. Ranked second globally in the S&P Global Corporate Sustainability Assessment 2024 for the aluminium industry, the company continues to position aluminium as the metal of the future in support of a more sustainable economy.
